RAISIN-DRYING TRAY.

Application filed March 1, 1923. Serial No. 622,140.

To aZZ whom it may concern:

Be it known that Orro A. REDDEMANN, a citizen of the United States,residing at Kerman, in the county of Fresno and State of California, hasinvented certain new and useful Improvements in Raisin-Drying Trays; andhe does hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to raisin drying trays and has for an object toprovide an improved type of tray which shall drain the accumulated waterfrom rains or other precipitation, to prevent the accumulation fromaffecting the raisins being dried upon the tray. It is well known inraisin culture that the grapes are picked and laid or piled upon devicesknown as trays, stand- 5 ing upon the ground in the vineyard. As

at present practised, these trays are preferably composed of wood, butthe wooden trays are expensive and comparatively few of the raisinproducers can afford to employ such trays. As a substitute for thewooden trays, raisin producers employ at present trays consisting of asheet of tough paper laid upon the ground with the fruit laid or piledupon the paper. Subject to turning and other manipulation, these trayswith fruit continue to lie upon the ground until the grapes have beencured to raisins.

The paper trays thus employed are satisfactory so long as there is norain or other precipitation but in view of the fact that the paper liesdirectly upon the ground which is, of course, uneven the weight of theraisins thereon depresses the paper into the depressions of the ground,forming depressions for the retention of water. Water contained in thesedepressions seriously affects the fruit, serving at some periods atleast to rot the fruit and at other periods to be detrimental to itsquality.

The present invention, therefore, is intended to replace the cheaper andmore ordinarily employed paper trays by a tray which will beself-draining and eliminate the necessity, as now practised, of goingover the vineyard with a sharp puncturing point to punch holes in thedepressed parts of paper to drain off the water.

To this end the invention comprises a sheet of paper shown inperspective at Figure 1 VIGWS.

As heretofore noted, the raisin tray which forms the subject matter ofthis application comprises a sheet of material 10. In practice thissheet will be paper, but the invention is not in any way limited topaper as a material, including any pliable sheet which may be providedwith the perforations 10 as shown. These perforations 10 will be spacedat such intervals as will insure the drainage of allsections of thesheet, irrespective of depressions by reason of the weight of thesuperposed fruit and the un evenness of the ground.

As shown at Figure 4;, bosses will be formed by the production of theperforations, such bosses providing, as will be noted, depressions ordishing immediately surrounding the perforations so that by employingslight care in the operation that side of the sheet containing thedishing will be uppermost, assisting in the prop-er drainage of thewater from the upper side of the 7 tray.

The employment of paper trays in raisin culture is so well understoodthat a further description will be unnecessary to a completeunderstanding of the use and opera.

tionof the device.

What I claim is:

A raisin tray comprising a sheet of flexible material havingperforations there through at spaced intervals, said perforationsforming depressions in the material surrounding saidv perforations andcommunicating therewith.

In testimony whereof he hereunto affixes signature.
